2 Current Ratings and Thermal

Due to the specific device construction, careful considerations about the thermal design of the in-package Hall-effect current sensor must be taken. High side current flows into the IC inside through the leadframe which typically has sub-milliohm level resistance, and as a result, heat is generated in the IC. In the TMCS family datasheet, there are several current ratings which correlate with different real working conditions.
